Description

On require of the package's main entry, index.js loads init.js which downloads a platform-specific executable from hardcoded oob-worker.*.workers.dev endpoints, with a DNS-TXT chunked fallback over *.dl.wel1.ru sub-domains (sdk/ext/pkg/net.dl.wel1.ru). The fetched binary is written to /tmp or %TEMP% under disguised names (.cache, dotnet_diag_.exe), chmod 755'd, and spawned detached via /bin/sh -c or cmd.exe. Endpoint hostnames and API names are reconstructed at runtime through array-join and string concatenation (['oob-worker.','cf103-070.worker','s.de','v'].join(''), require('child_'+'process'), fs['chmod'+'Sync']) to evade static scanners. A second dropper path with the same shape is present in lib/telemetry.js, loaded via the package main. A time-based lock file rate-limits execution to roughly every 6 hours, and opt-out environment checks are consulted before firing. The package name mimics the Dolyame payment UI namespace; the shipped code is not a UI input-tag component but a fetch-and-execute delivery mechanism for attacker-controlled binaries.
